standard exhaust end can loose

[sc0ttie]

I just came back from a ride out and when i went to feel if the silencer was still hot before i put my bike cover on, I was able to wobble the end can by just lightly pushing it in toward the wheel. I noticed this movement was happening at the point where the end can slips on to the black exhaust pipe. Is this normal this kind of movement only I have not noticed it before? Is my end can on its way out or already knackered?
